Radial profiles of abundances of species obtained with the updated model, in the text labelled as “Model 3” (solid), and with the original model (dashed) developed in Vasyunin et al. (2017). The profiles were obtained at the “best-fit ” time of 9.5 × 104 yr. For each radial point, the column densities of the species are divided by the corresponding column density of hydrogen (see Fig. 1). Then, convolution over 26′′ Gaussian beam is performed to mimic IRAM 30 m observations.
